I made the easiest DCC installation yesterday. I took the jumper plug out of PC board in Bachmann K4 tender. Then, I took a Bachmann Plug ‘n’ Play decoder & snapped it in! Only one problem, no lights! Can someone help me?
When you tell the engine to go forward, does it go backwards, by any chance?
One possibility is that you got the plug in the wrong way. The people that designed these did so in a way that you wouldn’t destroy anything if you got it backwards, but there would be problems. Depending on the decoder and engine, you may find that the engine runs backwards, or the lights don’t work. Try reversing the orientation of the plug and see if that fixes it.
Yup…plug probably is in backwards.

I agree with the others, it’s backwards!
